Two days good, one day bad

How bizarre this chemo thing is. After getting loaded up on Friday and then just wanting to sleep, Saturday and Sunday weren't bad. I was up and about at a decent hour, feeling not bad. I went to my wife's Granddad's birthday celebration and was sorely tempted to have a beer (although I was well behaved and didn't, for the sake of my overworked liver and kidney (although next week is another thing entirely)), so I must have been feeling pretty good.
Then, I wake up this morning and all I want to do is go back to sleep (nothing really new there, except I wanted to go back to sleep 'cus I was feeling rubbish). My head was banging and my energy was through the floor. Curiouser and curiouser, said I.
Anyway, I've dragged myself out of my pit and am sat downstairs, with the glorious weather beaming in through the windows and lightening my mood.
